UNPARALLELED LTD is one of the leading manufacturers and suppliers of granite structural components in China. With abundant experience, we warmly welcome you to buy advanced granite structural components made in China here from our factory. We also accept custom orders.
PRODUCT DETAILS
✔ Premium Material – Industrial-Grade Black Granite
Our precision components are crafted from carefully selected natural black granite-such as Jinan Black or Indian Black-with a material density exceeding 3050 kg/m³. Compared to marble, granite offers superior mechanical properties, including higher hardness, better thermal resistance, and long-term dimensional reliability.
✔ Hand-Finished to Micron-Level Accuracy
Every granite component undergoes precision hand lapping performed by skilled technicians with over 30 years of experience. This traditional process is combined with modern CNC technology to achieve surface flatness and parallelism within tight tolerances.
✔ Full Inspection with Certified Reports
All granite parts are thoroughly tested using advanced measuring tools, including laser interferometers, digital levels, and high-precision CMMs. We provide detailed inspection and calibration reports with every shipment, ensuring traceability and quality assurance.
✔ Large-Scale Granite Machining Capabilities
UNPARALLELED® is equipped to produce extra-large precision granite parts, with individual components reaching up to 12,000 × 3,000 × 1,000 mm. For modular or segmented applications, we also support precision splicing to deliver virtually unlimited lengths, ideal for semiconductor tools, optical inspection platforms, and large-scale metrology equipment.
Typical Applications
Precision measurement and inspection of shafts, rods, or cylinders
Tool setup and alignment
Support for cylindrical parts during machining or marking
Use in metrology labs, CNC workshops, and quality control departments

It's one of the hardest substances on the planet.
What is a granite base?
A granite base is a crucial component in the manufacturing of precision processing devices. It serves as a foundation for the highly sensitive components that make up the device, providing stability and rigidity.
What machine is used to cut granite?
Bridge Saws and CNC Machines for stone fabrication shops
A Stone or Granite Bridge Saw is a very large saw that runs on beam or bridge, to ensures quality professional cuts. Designed to be used by Stone Fabrication Shop, the saw cuts down large slabs into smaller pieces to fabricate a kitchen or bathroom countertop.
What do you need to drill into granite?
Take a drill bit designed for use on granite and install it on the drill. The drill bit must also be long enough to extend through the thickness of the granite stone. A diamond core bit can do the job very well.
